奈米鑽石於生物醫學與健康照護之應用

Applications of Nano-Diamonds in Biomedicine and Healthcare

鑽石不再只是高價的觀賞用飾品，比病毒更小的奈米級鑽石因其獨特的物理、化學、光學和量子特性，除了在尖端科技領域逐漸發展成極具潛力的奈米材料之外，奈米鑽石因具有很好的生物相容性、低毒性、表面積大且可調控其表面化學性質等優點，在生物醫學及健康照護領域逐漸展現出許多跨領域的應用。近年來，奈米鑽石已被運用於藥物傳輸系統，能有效提升藥物穩定性與靶向傳遞效率，並減少副作用，其出色的光學特性也使其成為次世代醫學影像與診斷工具的關鍵材料。此外，在牙科與骨科領域，奈米鑽石可用於提升生醫材料的機械強度與抗菌能力。在創傷護理與感染控制方面，其表面可攜帶抗菌分子，有助於預防傷口感染與促進組織修復。這些應用顯示奈米鑽石不僅可促進病患治療效果，也有潛力改善護理品質與臨床成效。本文將綜述奈米鑽石的主要合成技術（如爆炸法、高壓高溫法等），並聚焦介紹最近在臨床醫學與護理實務中的應用發展與研究成果，期能為未來奈米鑽石在健康照護領域的發展提供參考方向與啟發。

Diamonds are no longer confined to the realm of high-value ornamental gemstones. Nanoscale diamonds, which are smaller than viruses, possess unique physical, chemical, optical, and quantum properties. These characteristics have made them highly promising nanomaterials in advanced technological fields. Notably, nano-diamonds (NDs) possess excellent biocompatibility, low toxicity, a large surface area, and tunable surface chemistry, making them particularly attractive for a wide range of interdisciplinary applications in biomedicine and healthcare. In recent years, NDs have been increasingly utilized in drug delivery systems, where they enhance drug stability, enable targeted delivery, and minimize side effects. Their outstanding optical properties also render them key components in next-generation medical imaging and diagnostic tools. In dental and orthopedic applications, NDs have been
